A solar system sim from NatGeo.
I got three planets going at once. The two outer planets had huge orbits. It’s tough to keep the planets from hitting each other or pulling each other off course.
Awesome! This will take up my evening tonight.
I don’t know what physics they’re using, but it doesn’t appear to be Newtonian-- The Trojan points aren’t stable.
And the scales are absurdly wrong, and planets colliding aren’t completely annihilated; they merge.
Now I know why all the planets orbit in the same direction! heh!
One of my planets developed life. Then it got slingshot out if the system and it was wiped out. I wonder if it stays in a stable orbit long enough if it develops intelligence?
I love how my gas giant went whipping off into the void.
Pretty cool. I had a rocky/watery planet with it’s own dust planet moon develop life! It only lasted about 1500 years, before life was wiped out. Not sure what those little bastards were doing to kill each other off, but I’ve changed a few things and can’t get life again.
I managed to get a very stable orbit going, developed life, and kept it going for over 100,000 years. Then I went to pee, and when I got back, my planet had been destroyed.
Whee.
Can you get rid of that little blue planet? It keeps messing up my solar system.
“Where is your God now?”
This is cool. but a little boring. My little planet developed life almost immediately, and settled into an odd elliptical orbit (apogee is about twice the perigee). And went around. And around.
I’m just passing 150K years now, just waiting for that little blue object to kill it.
I finally got a couple planets in what seem to be non-terminal orbits.
However I’m guessing, the year temperature swings that I estimate around ±100,000 degrees are not conducive to the formation of life.
Mine is about 30 to one, In a spirography type period.
I started a system with two planets, a medium sized inner planet and a small outer planet. Initially, the inner planet had an orbital period of around 500 years and a fairly circular orbit at around 5 times its diameter from the Sun, the outer planet had a period of 2400 years and a highly eccentric orbit.
A near miss between the planets had the effect of lenghening the outer planet’s period to 9000 years and further increasing its eccentricity, but its period was later reduced to 5500 years by another near miss. These near misses increased the inner planet’s eccentricity so much that at perihelion it was only about 1/4 of its diameter from the Sun.
The inner planet had several near misses with the blue comet after its orbit’s eccentricity got increased - at one point the comet passed between the planet and the Sun when the planet was at perihelion - it’s a miracle that it went through cleanly!
After 33000 years, the inner planet got hit by a comet which sent it into the Sun; currently 77000 years have elapsed and the outer planet seems stable in its highly eccentric 5500 year orbit. Unsurpirisingly, no life has ever formed on either planet.
